@Palxan your lady knight looks way more like saber than those "plagiarisms of sabre" Also you do realize that those characters are nothing alike .. the nun is also from chrono crusade .. A series that aired a full 3 years before Fate:Stay Night. There is a chance they were inspired by the visual novel. But it's far more likely the characters resemblance is coincidental. As apart from the blond hair and the dress's color scheme they have nothing in common.

By all means take offense if you like but I hold to the assertion that the lady knight just looks like sabre in slightly different clothing. The hairstyle is almost exactly the same the face shape is the same the eye color is the same. Even a lot of the armor themes and motifs are the same.
